Bad Arc Contact

See the gnarly metal on the tip of the point on the left? That's where the arc touches down. The more gnarly it is (it gets like that with use), the less stable the arc is, and the image on screen will flicker.

Absolutely Perfect

Installation

It's a tight fit! Have to be careful not to ding the reflector. :/
Hope you've enjoyed these pictures.
After note: Once a new bulb has been installed, the bulb must be 'balanced' the process of making the bulb sit properly to ensure maximum and even light distribution on screen.
WIth digital projectors, this is an automatic process (you go through menue options and select 'Lamp LOC'). Easy. Old style projectors that run actual fim have knobs on the back the you must physically turn to adjust the bulb's orientation while looking at naked light on screen! Fun fun.
